Peter and I joked about how we were pushing electrons and thus saving gas when we skyped for our last tHAWT. On a related note (ahem), ponder this (via Bouphonia):
Downloading 56 minutes of music is more than two and a half times less
resource intensive than going to a shop to buy a CD, even if the music
is burnt on to a CD-R
That made me feel good about using iTunes! However, a commenter over at WorldChanging notes:
At first I bought into the same kind of thinking with paper - why
use paper, when I can haul around documents on my laptop? After all, my
laptop weighs the same whether the hard drive is empty or full. And
surely I was saving the environment by not cutting down all those
trees, right?
Now I'm not so sure.
The reason? A recent UN report that found that 1.8 tons of raw material
is required in the manufacture of the average computer. Looking at the
report, they only consider the impact for the purpose of obtaining the
music - but what about playing the music back? What about social
pattern differences that result once people start using computers? For
example: how many people just leave their computers on all the time
now? Wouldn't it be better to have a CD sitting on the shelf (ie: not
consuming power) than having a computer running all the time, awaiting
the moment a user decides to play back their digital files?
The report text itself points out that the material intensity data
is of low quality, so I think this report has to be taken with a grain
of salt. While the activity of getting music itself might be proven to
be more "environmental", the larger impact of computers, built from
highly toxic and difficult to separate materials can not be discounted.
From where I sit, however, the downloading of music isn't making me
use my computer or keep it on all the time--or maybe it's just not the
only factor. Anyway, computers ain't going away, so if
downloading music can reduce our impact on the environment a tad,
what's not to like?
